Problem 1: [10 marks in total] A hammer of mass 8.00 kg is attached with one end of a thin, light rod (Figure 1). A thrower accelerates the hammer from rest within four full turns (revolutions) and releases it at a speed of 21.0 m/s. Assuming a uniform rate of increase in angular velocity and a horizontal circular path of radius 1.20 m, calculate a) the angular acceleration, [2 marks] b) the tangential acceleration, [2 marks] c) the centripetal acceleration just before release, [2 marks] d) the net force being exerted on the hammer by the athlete just before release, [2 marks], and e) the angle of this force with respect to the radius of the circular path.[2 marks]
